 10 scientific surprises of Science News’ first 100 years

Antimatter, dark energy, plate tectonics and the role of DNA were unexpected discoveries

By Tom Siegfried

Contributing Correspondent SEPTEMBER 20, 2021 AT 9:00 AM

n 1929, Edwin Hubble (shown here at Mount Wilson Observatory) showed that more distant galaxies were
flying away from us faster than nearby galaxies, which suggested an expanding universe.

From the day Archimedes cut his bath short to shout “Eureka,” science has been a
constant source of surprises. 
Even after the abundant accumulation of knowledge in the intervening two millennia,
science still retains the capacity to astonish, and the century since Science News began
reporting has produced its share of shocking discoveries. Some such surprises happened
suddenly (if not necessarily with eureka moments); in other cases, revolutionary shifts in
understanding took a while to seep slowly into general scientific awareness.
In either case, Science News was sooner or later on the job during the last 100 years,
identifying and reporting the never-ending series of surprises, too numerous to mention
here, except for my Top 10./;../

Scientists pinpoint age of molten 'Einstein ring'

(ESA/Hubble & NASA/S. Jha/Acknowledgement: L. Shatz)

New science from a stunning 2020 Hubble image illuminates the back story behind a shining l
oop of light. 
The circle, also called an Einstein ring after the famous physicist who predicted its existence,
came about due to a galactic-scale illusion. The galaxy this so-called "molten ring" curls
around is called as GAL-CLUS-022058s and it is located in the Southern Hemisphere
constellation of Fornax, the Furnace.

As scientists affiliated with the Hubble Space Telescope wrote in a statement, the big ring is
actually a light smear created by a lensing effect that occurs when a foreground object with
strong gravity magnifies the light of a more distant galaxy behind it. New research suggests
that we are seeing the galaxy in the ring as it was about 9 billion years ago, when the universe
was only about one-third its present age of 13.8 billion years.

Para minha irmã Profa. Dra. Maria Helena C.A. que é Pós Graduada em Botânica, nos seus noventa e um, dei-lhe este livro, que agora estamos apreciando em conjunto. O que ela lê, comenta comigo em nosso encontro diário por vídeo. Eu tinha admirção pelo nome do Humboldt, mas sabia pouco de sua história. Esta Andrea Wulf está nos contando. Ela é autora premiada de vários livros sobre jardins e história natural.Nasceu na India, foi criada na Alemanha e agora vive na Inglaterra.

Alexander von Humboldt chamou atenção sobre a importância das florestas no enriquecimento da atmosfera e do controle da distribuição de água nos solos, humidade e temperatura ambiente, importância em evitar erosão dos solos, e o possível impacto imprevisível para as próximas gerações..

Thomas Jefferson o chamou de “um dos mais excelentes ornamentos de nossa época” Charles Darwin escreveu que “nada estimulou mais de formatão ardorosa o meu entusiasmo quanto a leitura na Narrativa Pessoal” dele. Sem ele não teria embracado no Beagle, tão pouco teria cocebido A origem das espécies.

William Worsworth, Samuel Taylor Coleridge e Henry David Thoreau, incorporaram seus conceitos de naturalista em suas poesia e outras obras (Walden) Simón Bolivar o chamou de “o descobridor do Novo Mundo”. Johann Wolfgang von Goethe, declarou que passar alguns dias com ele foi como “ter vivido vários anos”.

Nasceu em 14 de setembro de 1769 e morreu em 1859. Gerou inveja em Napoleão Bonaparte.

Ele dizia que “a Terra é um só organismo interconectado que pode ser catastroficamente danificado por nossas próprias ações” (NY Times)

Pump: A Natural History of the Heart Bill Schutt Algonquin (2021)

Rich in meaning and metaphor, the word ‘heart’ conjures up many images: a pump, courage, kindness, love, a suit in a deck of cards, a shape or the most important part of an object or matter. These days, it also brings to mind the global increase in heart attacks and cardiovascular damage that attends COVID-19. As a subject for a book, the heart is an organ with a lot going for it.

Enter zoologist Bill Schutt. His book Pump refuses to tie the heart off from the circulatory system, and instead uses it to explore how multicellular organisms have found various ways to solve the same fundamental challenge: satisfying the metabolic needs of cells that are beyond the reach of simple diffusion. He writes of the co-evolution of the circulatory and respiratory systems: “They cooperate, they depend on each other, and they are basically useless by themselves.”/.../

Mars is the solar system's near-miss world. Thanks to data from rovers and other spacecraft, we know that the Red Planet once fairly sloshed with water—with dry deltas, riverbeds, and sea basins stamped into its surface. But 4 billion years ago, the Martian core cooled, shutting down the dynamo that sustained its magnetic field. That left the planet vulnerable to the solar wind, which clawed away the atmosphere, and allowed the Martian water to escape into space.
